SPECIFICATION forming part of Letters Patent No. 792,479, 4datedJ' une13, 1905. Application filed June 6, 1904. Serial No. 211,443.

To (1J/Z 71171/0122, zit may concern:

Be it known that we, EUGnN TIMM and TIL- HELM RUNGE, merchants, subjectsof the Emperor of Germany, residing at Sophienstrasse 5 52, in the freetown of Hamburg, in the Empire of Germany, have invented certain new anduseful lImprovements in Gas-Pressure Regulators, of which the followingis a full, clear, and exact description.

This invention has reference to appliances for regulating the pressureof gas in gas-receptacles in connection with which the admission of gasinto the gas-holder bell is regulated by means of a valve arranged overthe I5 mouth of the gas-inlet pipe and governed by the bell by means ofa two-armed lever.

The invention comprises a regulating-valve actuated by a weight on thegas-bell to open the inlet-pipe and actuated by the weight of 2O thevalve itself to close the inlet-pipe when the gas-bell rises.

ln the accompanying drawings, Figure lis a vertical section of agas-regulator made in accordance with our invention. Fig. 2 is a detailside view of the valve.

The gas-holder a consists of a closed container having an inner wall rt'and a bottom fr, the inlet-pipe l and the outlet-pipe j) leading intosaid bottom, as shown. The gasometerbell c is placed within the holderwith its lower open end disposed between the walls (t a of the holder.Depending centrally from and within the gasometer-bell is a rod having aweight at its lower end, and at the top of 3 5 said bell a tube issecured, which serves as a guideway for a short rod depending from thetop of the holder (t. Rising from the bottom ff? of the holder wy is abar f, and pivoted to this bar is a lever 7e, carrying at one end a 40stop valve or cap f/. The outer or free end of the lever /L is providedwith a depression or recess A weight f is formed on or connected to arod depending from the upper wall or top of the bell c, and this weightis designed to engage the recess 2f in the lever /t and lift the valve yas the bell c descends. The lever /1/ is so balanced that the armprovided with the stop-valve g is heavier than the arm terminating inthe recess t', so that under ordinary circumstances the gas-inlet pipeZ, over which the stop-valve g is arranged, is kept closed by thelatter.

The valve may consist of a receptacle m, filled with mercury andarranged around the upper end of the gas-inlet pipe Z, into which theValve g, which is in the form of a cap with holes 0 close to its bottomedge, is immersed. As long as the holes o in the valve g are completelyimmersed in the mercury no gas can enter through the pipe Zinto thegas-receptacle. If, however, the bell falls upon gas being taken out ofthe gas-receptacle through pipe p, the weight descends onto the recessz'of lever 7a, and by its weight depresses the recess t', and the valve,f/ rises, so that as soon as the holes 0 are only partly above themercurial liquid gas can enter into the gas-receptacle through the pipeZ. This continues until the weight le in consequence of the rising ofthe bell c is raised by the latter off the recess i, whereupon theoperation is repeated in the same manner by the subsequent descent ofthe bell when gas is taken from receptacle. Glycerin is introduced intothe receptacle in any suitable way.

Having thus described our invention, what we desire to obtain by LettersPatent and claim is* A gas-pressure regulator comprising a gasbell, aweight depending from the dome of the bell, a lever pivoted within thebell, said lever having pivoted to one end thereof a perforated cap orvalve, a mercury-chamber surrounding the gas-inlet pipe and forming adash-pot for the valve or cap, and the opposite end of said lever havinga recess to receive the depending .weight as the bell descends,substantially as described.

In witness whereof we subscribe our signatures, in presence of twowitnesses, this 9th day of October, 1903.
